GRAIN-DOOR FOR RAILWAY-CARS.

Application filed July 9, 1918.

same.

The invention relates to grain doors for railway cars and has provided a simple and efficient door that may be mounted in the doorway of the ordinary grain car to retain grain within the car.

It is essential in grain doors that the door it between the facing edges of the door opening and over the interior of the walls of the car on either side of the door opening, that the door may be easily lifted when the car is filled with grain, and that the door be securely locked in closed position to hold the grain.

The present invention has provided an improved grain door to rest within the door opening and flanges to extend over the in terior face of the walls surrounding the door opening, together with means for looking the door in closed position and means for lifting the door.

Nith these and other objects in view, the invention consists in the features of construction, combinations and arrangements of parts hereinafter set forth and more particularly pointed out in the append d clann, the accompannying drawings illustrating a form of the invention.

In the drawings Figure 1 is a fragmentary exterior view of a railway car with the improved grain door applied.

Fig. 2 is a fragmentary interior view of a railway car with the improved grain door applied.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig. 41 is a sectional view taken on line 4-4 of Fig. 2.

Fig. 5 is an enlarged fragmentary sectional view taken on line 5--5 of Fig. 1.

Fig. 6 is an enlarged fragmentary view of the main member of the locking mechanism.

bers 7 and 8 are all of common and well known construction.

The rain door 9 rests upon the floor 4 and outward against the inner walls 2, and between the facing faces 10 of the door opening 11, so that the weight of the grain against the door when the car is loaded tends to press the door outward against the interior surface of the inner walls, and the faces 10 of the door opening prevents the door from moving or shifting longitudinally of the car.

Secured to the door 9 by the bolt 12, is the main locking member 13 pivotally mounted on the bolt and spaced from the door by the washer 1d, and provided with the downward extending arm 15 to engage in the slot 16 of the plate 17, the upwardly extending arm 18 which is bent outwardly at an approximately right angle at 19, and the arms 20, the latter arms being provided with the holes 21 to receive the pins 22. Only one of the holes 21 in each of the arms 20 is employed in connection with one size of grain door, the duplicate holes being to serve different sizes of grain doors so that one size of the locking member 13 will answer for variuos sizes of grain doors without changing the length of the lockting bars 22.

The locking bars 22 are provided with the slots 23 and 2d, the pins 25 passing loosely through the slots 23 and being secured in the holes 21, while the pins 26 pass loosely through the slots 24 and are secured in the plates 2'7 mounted on the grain door 9, the bars 22 being free to play to and fro on the pins 25 and 26 as the locking member 13 is moved from the position shown in full lines of Fig. 1 to that of the dotted lines of the same figure and retained.

When the locking member 13 is in the position shown in full lines of Fig. 1 the downwardly extending arm 15 is engaged in the member and connecting parts in locked position, the pin 31 being removed when it is desired to unlock the door. The pin 31 is connected to the door 9 by the chain 32 so that the pin will not become lost or misplaced when removed from the bracket 30 and arm 18 to unlock the door.

The hole 33 is provided in the outer wall 1 and adjacent sill 5 connecting to the slot 16 in the plate 1? for the purpose of allowing any substance, as water or grain, that may enter the slot to pass out so that the slot will not become filled with water and rot the sill, or filled with grain or other solid substances and the slot rendered incapable of admitting the arm 15.

The pulleys 3d are journaled on the bolts 35, the bolts being secured in the root timbers 7, the guard plates 36 being secured at the respective ends thereoi by the same bolts, while the outer ends oi the cap plates are se cured to the timbers by the bolts 37 which together with the cap plates prevent rope 38 from becoming misplaced or moved from around the pulleys.

The rope 38 passes over both the pulleys and the ends 39 oi. the rope are secured to the main door 9 so that the portion of the rope between the pulleys may be pulled downward to raise the door 9, the nut 40 on the bolt 12 forming a convenient place to engage the rope looping under the nut to hold the door in elevated and open position. i

It will be understood from the foregoing that the door 9 may be lifted slowly or tie ' gradually as the grain runs from the car underneath the door and when the grain Wlll no longer run from the car the door may be hooked in elevated position as shown.

in dotted lines of Fig. 4, with the hooks il depending from. one of the timbers 8 engaged in the staples l2,'the staples being secured to the door, and the hooks 43 rigid with the door engaged in the staples 44,

the latter being secured to the door posts 3 of the car.

When the door 9 is suliiciently elevated by the rope 38 the lower edge 45 of the door may be lifted to the position shown in dotted lines ofllig. e and as the door is so lifted the hooks 43 will automatically engage in the staples 44 after which the hooks all may be engaged with the staples l2.

From the foregoing it will be understood that the improved grain door will fill the door opening longitudinally of the car and overlap the inner walls of the car so that the pressure of grain against the door from within the car will tend to hold the door rigidly closed so that no grain will leak past or around the door, the bars'22- and the arm 15 will lock the door securely closed, and the door may be lift-ed and secured in open elevated postion so that the car may be loaded with other forms of merchandise without removing the door from the car.

What I claim as new, and desire to secure by Letters Patent, is z- Ina grain door for railway cars, a railway car body, a door opening in said body, a door closing the lower part of said door opening, a plate pivotally connected to said door, lock bars pivotally connected to said plate and reaching beyond said door When in locked position, a plurality of holes in said plate for adjusting the pivotal connection of each of said lock bars so that one pair of lock bars will serve various sizes of grain car doors, said lockbars Withdrawable to within the scope of said door by rotating said plate, and means on said car body to be engaged by said lock bars.
